معرفی
Sven Wedemeyer is a Professor at the Institute of Theoretical Astrophysics, University of Oslo, and a Principal Investigator at the Rosseland Centre for Solar Physics (RoCS), a center of excellence funded by the Research Council of Norway since 2017. He serves on the Institute board of the Institute of Theoretical Astrophysics as a permanent academic staff member (from January 2025) and is the PhD committee chair at the Institute. Internationally, he is a Member of the Council of the European Astronomical Society (EAS, since July 2024), a Co-opted board member of the European Solar Physics Division (ESPD) of the European Physical Society (EPS, since September 2024), and the EAS representative for ASTRONET (since October 2024). He also serves on the Advanced Grant (PE9) evaluation committee for the European Research Council (ERC AdG 2023) and the MSCAA/ERC reference group of the Research Council of Norway (since 2020).
Professor Wedemeyer's research focuses on solar and stellar physics with additional interests in extrasolar planets. His work primarily utilizes realistic numerical simulations in comparison with space-borne and ground-based observations. His current major research activities include solar/stellar science at (sub-)millimeter and radio wavelengths, studies of the solar chromosphere using ALMA observations, and investigations into stellar activity. He is a lead of the solar/stellar science working group for the AtLAST consortium (The Atacama Large Aperture Submm Telescope) and coordinates an international team studying vortex flows in solar plasmas funded by the International Space Science Institute in Bern, Switzerland. His research has produced significant findings, including the discovery and explanation of magnetic tornadoes on the Sun, featured on the front page of Nature in 2012.
His publication record demonstrates a strong focus on advancing observational techniques for solar and stellar physics at millimeter wavelengths, particularly through the Atacama Large Millimeter/submillimeter Array (ALMA). His recent work shows an increasing emphasis on connecting solar observations with stellar phenomena, developing new diagnostic tools for solar-stellar activity, and contributing to the development of next-generation telescopes like AtLAST. The interdisciplinary nature of his research spans solar physics, stellar astrophysics, and exoplanet science, with a consistent methodological approach combining numerical simulations with multi-wavelength observations.
- ERC-funded SolarALMA project (2016-2021)
- Initiator and co-ordinator of the SSALMON research network (since 2014)
- Discovery of magnetic tornadoes on the Sun featured in Nature (2012)
Professor Wedemeyer has led multiple significant research projects including the EMISSA project (funded by the Research Council of Norway, 2019-2023), the ESO-funded ALMA Development Study 'High-Cadence Imaging of the Sun' (2018-2023), and the ERC-funded SolarALMA project (2016-2021). He serves as Norwegian representative at the Observing Programme Committee of the Nordic Optical Telescope and is actively involved in multiple international research networks including KOINet for exoplanet observations and the Extreme Precision Radial Velocity group. His leadership extends to coordinating the international team 'The nature and physics of vortex flows in solar plasmas' funded by the International Space Science Institute since 2018.
Professor Wedemeyer leads the solar/stellar science working group within the AtLAST consortium and is instrumental in developing solar observing modes for ALMA. His work with the SSALMON research network connects over 80 researchers worldwide focused on solar simulations for millimeter observations. He also contributes to the Solar ALMA Science Archive (SALSA) and the Solar ALMA Library of Auxiliary Tools (SALAT), creating essential resources for the solar physics community working with ALMA data.
